Abort pending deletion on IndicesService close

When IndicesService is closed, the pending deletion may still be in
progress due to indices removed before IndicesService gets closed. If
the deletion stucks for some reason, it can stall the node shutdown.
This PR aborts the pending deletion more promptly by not retry after
IndicesService is closed.
